  • 1997-11-12 Barium Compounds As Federal Hazardous Air Pollutant
    BARIUM COMPOUNDS CAS Registry Number: 7440-39-3 Ba Molecular Formula: Ba Barium is an alkaline earth metal which occurs in yellowish, silver-white, slightly shiny lumps. It is slightly malleable and very oxidizable. Solutions of soluble barium salts are a white powder with sulfuric acid or soluble sulfates (Merck, 1989). The powder may ignite or explode in air or other oxidizing gases and should be stored under inert gas or petroleum (Sax, 1989). Barium is soluble in alcohol and insoluble in benzene (HSDB, 1993). Examples of Barium Compounds Barium acetate Barium cyanide Barium iodate Barium acetylide Barium cyanoplatinite Barium nitrate, nitride Barium azide Barium diazide Barium oxide Barium benzoate Barium dichromate Barium peroxide Barium bromate Barium ferrite Barium rhodanide Barium caprylate Barium fluorborate Barium silicofluoride Barium carbide Barium fluoride Barium stearate Barium carbonate Barium hydride Barium sulfate, sulfide Barium chlorate, chloride, Barium hydroxide Barium thiocyanate chlorite Barium hypophosphite Barium zirconium (IV) oxide Physical Properties of Barium Synonyms: none Atomic Number: 56 Valence: 2 Atomic Weight: 137.33 Boiling Point: 1600 oC Melting Point: 710 oC Density/Specific Gravity: 3.5 at 20 oC Vapor Pressure: 10 mm Hg at 1049 oC (Merck, 1989; Sax, 1989) SOURCES AND EMISSIONS Toxic Air Contaminant Identification List Summaries - ARB/SSD/SES September 1997 87 Barium Compounds A. Sources Barium is emitted mainly from mining and refining industrial processes, in the production of barium chemicals, and as a result of combustion of coal and oil (HSDB, 1993). It is used as a catalyst for organic reactions, as a lubricating oil additive, as rat poison, in the manufacture of paper electrodes, in fireworks, and in electroplating (Proctor, 1991).

  • Wouter Visser Pyro Formula Compilation
    Important note: It is impossible to give a finite set of rules that will assure your safety in pyrotechnics. Described below you will find just some of the most important and common ('everyday') things that should always be kept in mind when handling pyrotechnic compositions and chemicals. They apply to a wide variety of compositions. But every composition is different. Some must be rammed or pressed to work properly. Other will explode when rammed. Some must be wet with water, others may spontaneously ignite when wet. Some mixtures are relatively safe to use by themselves but are extremely sensitive when used together. (A number of well known 'incompatible' mixtures and chemicals are also listed below). The point is: remember and think about the rules below, they are important, but realize any such list is inevitably incomplete. Accidents happen even in places where every conceivable safety precaution is taken. We don't guarantee your safety if you follow the rules below (also read the disclaimer), but merely say it is wise to do so. It'll increase your safety. Disclaimer I accept no responsibility for persons harmed or injured or for any damage caused by devices like rockets, igniters, propellants etc. made on the basis of information presented on the following pages. Information presented herein is for informative purposes only. Also note that although we have tried to give comments on safety aspects of the described procedures, but we may have forgotten things or have been inconsistent. Keep that in mind at all times. Use your common sense, and use more than one reliable source of information before doing anything.
